Heh, EMACS or vi ? :-)

Yes. By the way, even if it's off-topic, I would be interested in
knowing what it is that you dislike about OpenCASCADE. In the
context of the project I mentioned, we're also looking for a Free
CAD system, and some of the ones based on OpenCASCADE look very
promising. It would be good to know if there are any issues with
the technology before we commit ourselves to one of the choices.

That would be possible, yes. But how about just putting it all in
a separate function with a warning that this isn't something one
should consider a good example ?

I've attached a patch that does this. The change to WinEDA_App::OnInit
is quite small. I also noticed that dialogs now cause the window to
be created. Not sure what happened, but it's a welcome surprise :)

Thanks,

This patch adds a command-line option --plot to eeschema that makes it
run File -> Plot -> Plot PostScript -> Plot ALL on the specified file.
It also prevents eeschema from opening a window and from checking for
concurrent instances.

This lets shell scripts generate plots, i.e., of schematics that have
been processed by these scripts.

Known issue: if there is an error or a warning, eeschema will bring up
a dialog instead of just exiting.

This patch is for KiCad SVN revision 1771.
